The Role of Certain Congenital Infections in Aplastic Anemia and Prognostic Value of Fetal Hemoglobin as a Follow-Up Marker

Background: TORCH infection has a role in aplastic anemia (AA). Fetal hemoglobin may be high in certain acquired hematological conditions such as aplastic anemia. We conducted this study to evaluate the correlation between certain congenital infections and severity of aplastic anemia and to study fetal Hb as a follow up marker during treatment of aplastic anemia. The aim of study was to correlation between certain congenital infection and severity of aplastic anemia and to study of hemoglobin F (HbF) as a follow up marker during treatment of aplastic anemia.

Methods: Our prospective study was conducted on 20 children aged up to 18 years diagnosed with aplastic anemia following either bone marrow aspiration or biopsy that proves bone marrow hypocellularity with absence infiltrative BM disease or inherited BM disease recruited from Pediatric Hematology-Oncology Unit of Tanta University Hospital. Patients were classified according to level of HbF in to high HbF group and normal HbF group.

Results: TORCH infections were detected in certain numbers of patients . HbF decreased in high HbF group after treatment. There was significant increase in CBC parameters in high HbF group than normal HbF group after treatment. There was insignificant decrease in mortality in high HbF group than normal HbF group. Mild to moderate cases were significantly higher with TORCH IgM +ve cases

Conclusions: Acquired AA is associated with TORCH infection. In treated cases of AA, improvement of hematological parameters is associated with high HbF and from these results, it can be used as a prognostic marker to monitor the successful response of these cases to the used line of treatment.
